In this dialogue, you can adjust simulation or treatment program generation settings prior to starting the process. For further usage tips and instructions, please see the Heureka Help. [[1]]

RegWise

The following options and settings are available in the dialogue window Simulation:

Select Result Variables: Allows selection of which result variables to store in the result database.
Start year simulation: (to be added)
Reference year: Adjusts the year to which the underlying indata is projected.
Simulation name (optional): Allows naming the simulation.
Max periods: Sets the number of periods for which the simulation results will be stored.
Random seed:
The random seed is used in stochastic models if any stochastic models are enabled in the control tables. The random seed sets the order in which random numbers are drawn from random number generators. Thus, different seeds will generate different results from stochastic models. If the random seed is set to zero the seed itself will be randomly generated.
The random seed will not affect the outcome of deterministic models.
Random seed Control Categories: Random seed for stochastically assigning treatment units within a forest domain to control categories.
Discount rate (%): Real discount rate used for calculating net present values.
Additional periods: (to be added)
Log trees to file: Allows storing tree results to files for detailed analyses and scrutinizing.

PlanWise

To be added.
